This truck has never shifted normal to me, I work at GM and have owned many trucks. This definitely doesn't shift smoothly at all. Always was jerking and then it slipped and started making a whining noise and driving down the highway it just lost power and the tach was jumping.

I pulled over and turned it off and the battery was dead. Towed it home, replaced battery and still no gears at all. No 4x4 either. It would move if you started the engine and quickly put in gear, but only for a few seconds and then would quit.

The transmission guy said the filter was full of metal and shutting down the pump. 5k to replace, this is absolutely ridiculous for only having 91k miles. Extended warranty ran out at 72k. GM needs to own this, these vehicles have become so over priced and the reliability has certainly fallen short. It seems they're just not built to last anymore. They just want to keep you in debt by always needing to replace them.

GM for many years had a 100k warranty on the drivetrain. You will now notice extended warranties are very expensive. That's because of the high failure rate. They also, no longer honor the employee discount. My next vehicle will not be GM. Many of my friends at work have done the same and bought others.

What I can't believe is why was only the 8 speed transmission part of the class action suit? This transmission clearly has an extremely high failure rate. The average @120k miles from what I have researched and confirmed by transmission shops. All say they currently have a 2014-2017 Silverado in their shop getting a transmission now!
